The following paper seems APLicable here. Jeremy Gibbons also
gave a delightful talk on this.

"APLicative Programming with Naperian Functors"
https://www.cs.ox.ac.uk/people/jeremy.gibbons/publications/aplicative.pdf

    We show here that such a custom language design is
    unnecessary: the requisite compatibility checks can
    already be captured in modern expressive type systems, as
    found for example in Haskell; moreover, generative
    type-driven program- ming can exploit that static type
    information constructively to automat- ically induce the
    appropriate liftings. We show also that the structure of
    multi-dimensional data is inherently a matter of Naperian
    applicative functors -- lax monoidal functors, with
    strength, commutative up to isomorphism under
    composition -- that also support traversal.
